FlexPhones Master Installation and Operation Manual

DESCRIPTION

Product Description:

The FlexPhones Master is a professional Broadcast/Studio six channel dis-

tributed headphone system with independent talkback capabilities. Each of the six

channels provides stereo program monitoring and selective talkback with intercon-

nection via CAT5 cable to multiple Active Headphone Remotes (AHR-1) and/or the

Monitor Selector Interface (MSI). Multiple masters may be cascaded to form larg-

er systems. The FlexPhones Master is equipped with inputs for stereo program and

talkback audio. Rear panel program and talkback trimmers are provided to pre-set

maximum input levels. The microphone/line level talkback input is available via a

rear panel plug-in euroblock connector, while the front panel XLR connector facili-

tates the use of a user provided gooseneck microphone or headset. The front panel

is equipped with a level control for local headphones with both 1/4” and 1/8” stereo

headphone jacks. The six front panel talkback switches allow the user to independ-

ently communicate with each AHR-1 listener and can be configured to insert talk-

back audio into only the left or both ears and dim either or both program channels.

Any combination of switches may be pressed, while the “All-Call” interrupts all lis-

teners. The Talkback function can be remotely controlled. Six RJ45 jacks are pro-

vided to distribute audio and power via CAT5 cable to the AHR-1’s, and/or MSI’s

FlexPhones Master Installation and Operation Manual

INSTALLATION

Installation:

Please examine your FlexPhones Master and/or AHR-1 carefully for any

damage that may have been sustained during shipping. If any is noted, please noti-

fy the shipper immediately and retain the packaging for inspection by the shipper.

The package should contain the FlexPhones Master, 16vac@600ma wall power

transformer, two CAT5 cables and this manual.

Installation of the FlexPhones Master in high RF environments should be

performed with care. Shielded cable is suggested for all audio connections.

All shields should be tied to the EGND terminals. The station ground should

be connected to the chassis ground screw located on the far right side of the

FlexPhones Master as viewed from the rear. It is recommended that all cables con-

nected to the FlexPhones Master be looped through ferrite cores to suppress RF.

Surge protection with RF filtering is also suggested for the wall transformer. The

purchase of an inexpensive UPS will provide back up in case of power outages.

Connections are via plug-in euroblock connectors and RJ45 connectors.

Remove the connector from the header; remove about 1/8” of insulation from each

wire. Insert the wire into the desired terminal and then tighten the screw. Be sure

no bare wires are exposed. Reinstall the connectors.

Stereo Program Input

Normal program audio should be connected to the + and - inputs for balanced oper-

ation, or to the + input and grounding the - side for unbalanced input operation on

TB1 (bottom). Audio levels should be between -15 and +4dBu.

Talkback Audio Input

Mic or line level audio should be connected to the + and - inputs for balanced oper-

ation, or to the + input and grounding the - side for unbalanced input operation on

either TB1 (top) or the front panel XLR connector. Audio levels should be between

–60 and –30dBu in MIC position or –15 and +4dBu in LINE position. JP1 and JP2

are used to set the talkback input for either MIC or LINE levels. Follow the jumper

layout in the appendix to set these two jumpers to the desired position. The factory

default is set to MIC.

Talkback Audio Output

The unbalanced output can be used to feed additional FlexPhones Master

talkback inputs. Connections to TB1 (top) can be made to the + output and ground

for unbalanced output operation.

NOTE:

For proper installation,

follow the silkscreen

labels on the rear

panel.

FlexPhones Master Installation and Operation Manual

INSTALLATION

DIM jumper configuration

Removing either or both of the Dim jumpers mutes the program audio dur-

ing a talkback session, while inserting either or both will dim the program audio

approximately 20db below normal program levels. Use the table below along with

the jumper layout sheet in the appendix to properly configure. Factory defaults have

these jumpers installed.

Right ear talkback enable jumper:

In a talkback session, talkback audio is always feed into the left ear. Placing

a jumper over the desired header will enable talkback audio in the right ear. Use the

table below along with the jumper layout sheet in the appendix to properly config-

ure. Factory default has these jumpers installed.

(switch, contact, open collector) with a jumper between 1 & 2 and another jumper

over 3 & 4. To change the input to WET (user supplied voltage between 5 and

24vdc), remove both jumpers and place ONE jumper over pins 2 & 3. Use the table

below along with the jumper layout sheet in the appendix to properly configure.

! NOTE: Refer to the schematic diagram for the proper polarity when attaching

equipment to each input.

FlexPhones Master Installation and Operation Manual

INSTALLATION

Cable Interconnection

After completion of the jumper set-up and the audio connections have been made,

connection of the CAT5 cable can be started. Connect the user supplied CAT5 cable

between the desired channels (follow the numbers on the chassis) rear panel RJ45

on the FlexPhones Master and each AHR-1 and/or MSI. Up to two AHR-1’s or one

AHR-1 and one MSI can be daisy-chained from each RJ45 on the Master.

Program Level Setup

Turn the rear panel “Master Pgm Lvl” trimmer CCW. Set all headphone

level controls to 1 o’clock. Plug a set of headphones in to either of the AHR-1’s

headphone jacks. Feed the desired program level into the Master and adjust R2 the

rear panel “Master Pgm Lvl” trimmer for the desired level. This also holds true for

the MSI.

Talkback Level Setup

Turn the rear panel “T/B Lvl” trimmer CCW. Plug a set of headphones in to

either of the AHR-1’s headphone jacks. Hold down the talkback channel button that

the AHR-1 is connected to and adjust the “T/B Lvl” trimmer R21 on the rear panel

of the master for the appropriate talkback level. Depending on the configuration for

each channel, the program audio will be muted or dimmed in each ear, while the

talkback will be present on either or both ears. This also holds true for the MSI.

Microphone Phantom Power Jumper

To power microphones needing phantom power; install the supplied jumper

over JP36. JP36 is supplied but not installed. 15vdc is supplied when installed.
